i just finished wiring up my car and it fires right up and idles perfect, but after about 30 seconds it sputters and dies. now while its running it wont rev up it just sputters really bad. I have gotten a code for a coolant temp sensor and got one for a map sensor once but then after i checked everything i reset the ecu then i only have gotten the coolant temp sensor code. If i pull the vacuum line off the map and plug it the car will rev easier. i only did this once just to see what happend i didnt continue to do it i know i need the map.lol any ways any ideas. i am going to pull the coolant temp sensor and try to find another one. i have had a couple of coolant temp sensors co out on me and the cars ran like shit. btw it it is two wire sensor for the ecu not the one for the gauge. thanks for the help

okay figured it out had an issue with the coolant temp sensor and the FPC wire was wired to the ecu but wasnt running the pump. i grounded it and it runs champion now.

oh yeah i sure do love it but the thing smokes like crazy if get into boost at all. i ran a compression test and i have 190psi from front to back with no difference between cylinders. thing runs awesome and still builds boost but smokes crazy. im sure the twins are dead. looks like it may have to go single sooner than i thought.lol
